<p>A fluid film lubricated thrust bearing comprises a rotatory member (12) such as a thrust collar on a shaft subject to axial load (18) and shoes (10) of elastomeric material (20) for reacting the axial load. Starting of rotation when the member (12) is subject to load is enabled by tilting the faces of the shoes against which the rotatory member (12) runs e.g. by interposing a wedge-shaped backing (22) between the elastomeric material (20) and a support or backing member (14) to assist formation of fluid films as the member (12) rotates. Introduction of pressure fluid between the members (12, 14) can provide hydrostatic reaction of the axial load (18) and further reduce starting torque. The fluid may be oil or water.</p> |
